From version 4.4, Artifactory supports SSH authentication for Git LFS and the JFrog CLI using RSA public and private keys. This allows these tools to exchange sensitive information with the Artifactory server that is authenticated via SSH.
There are two main facets of SSH authentication:
Server authenticates itself to the client
The server must be authenticated before you send it any confidential data. For example, you should not authenticate a user to the server with the user's password before the server has been authenticated. The server is authenticated in the following manner.
When the SSH connection is established, the server sends its public key to the client, and the client matches the key to a list of known public keys stored in a
known_hosts file. (Before the first ever connection to the server, you must obtain the server's public key by some other means and add it it to the
known_hosts file manually). This verifies that the server is indeed the owner of the stored public key, since only that server will have the corresponding private key. It also verifies that the server is known (and not an imposter) since its public key is stored in the
User authenticates itself to the server
This process mirrors the process of the server being authenticated to the client. The user must first provide his public key to the server which stores it in the user's account authorization list. Then, when the user tries to log in, the server sends the user back his public key, and the user must show that he holds the corresponding private key.
SSH is not supported if using Artifactory Saas cloud service.
To configure SSH authentication, you need to execute the following main steps:
In this step you will configure Artifactory's SSH authentication parameters. First you need to generate an SSH key pair for Artifactory. For example, on a Linux-based system, you could execute the following command:
Then, to configure Artifactory for SSH authentication, in the Admin module, select Security | SSH Server and fill in the required fields.
Enable SSH Authentication

First, you need to generate a key pair. For example, on a Linux-based system, you could execute the following command:
